The San Juan market is Mexico City's most famous deli of exotic meats, where an adventurous shopper can hunt down hard-to-find critters […] But the priciest items in the market aren't the armadillo steaks or even the bluefin tuna.

(fish) A slice of meat cut across the grain (perpendicular to the spine) from a fish.

Really large bass can be treated as filets, as we mentioned earlier, or they can be steaked. If they are to be steaked, they should be cleaned like a bass to be baked, scaled, and the skin left in place.
